W.A.Khan, 1/5/2013, Samsung Galaxy S II The Samsung Galaxy S II boasts a beautiful display and a thin design. With a dual-core processor, the Gingerbread device delivers fast performance, as well as good battery life. Camera quality is excellent.
But, Some parts of the phone feel flimsy.
The bottom line: With its dual-core processor, vibrant display, and great performance, the sleek and powerful Samsung Galaxy S II rises as AT&T's top Android smartphone. Specifications

Diagonal screen size4.3 in Price;$312.00 VS Apple iPhone 5 The iPhone 5 adds everything we wanted in the iPhone 4S: 4G LTE, a longer, larger screen, free turn-by-turn navigation, and a faster A6 processor. Plus, its top-to-bottom redesign is sharp, slim, and feather-light.
But, Apple Maps feels unfinished and buggy; Sprint and Verizon models can't use voice and data simultaneously. The smaller connector renders current accessories unusable without an adapter. There's no NFC, and the screen size pales in comparison to jumbo Android models.
The bottom line: The iPhone 5 completely rebuilds the iPhone on a framework of new features and design, addressing its major previous shortcomings. It's absolutely the best iPhone to date, and it easily secures its place in the top tier of the smartphone universe. Specifications

Diagonal screen size4 in Price;$149.99 to $715.00 VS BlackBerry Z10 The Z10 is a decent smartphone offering up a strong range of features and a fancy new operating system that may catch the eye of the technologically adventurous.RIM dug deep to give the slick-looking BlackBerry Z10 enough features to satisfy both consumers and professionals -- like a good camera and a sharp user interface.
But, The Z10's unintuitive gesture paradigm creates a learning curve, and a long list of OS inefficiencies and omissions sour the experience. The bare-bones maps app and a deficit of camera features are two examples.
The bottom line: Though it's not quite enough to draw committed iPhone or Android owners, the BlackBerry Z10's modern design and features give BlackBerry fans what they've hungered for. Specifications

Diagonal screen size4.2 in Price;$14.99 to $799.99 VS Nokia Lumia 920 The Nokia Lumia 920 forges new Windows Phone ground with wireless charging support and a highly sensitive screen you can use with gloves. Moreover, Nokia helps fill in Windows Phone OS gaps with a few missing features.
But, A thick, heavy build and slippery finish for some colors make the Lumia 920 harder to hold and carry, and the phone's overhyped camera doesn't have enough settings.
The bottom line: Nokia's Lumia 920 is heavy and thick, but if you want the most powerful, feature-rich Windows phone available, this is it. Specifications
